Three-phase electricity monitoring and control
is the most important factor to consider in electric power distribution
networks and more especially for industrial electric motors and machines that works only with three
phase lines. If any of
the three phase line fails, the three phase motor winding will draw more current
than the other and excess heat will be generated causing deterioration of the
motor insulation. This can permanently damage the motor due to phase
failure. Phase failure and unbalanced voltage can damage electric
motors. They are the two important problems that always effect smooth
running of three phase motors after installation. Phase failure can be said to
occur when any of the three phase line is being cut off, while unbalanced voltage
is when there is a critical over voltage or under voltage in the three phase lines. It is a very big risky for electric motors when they continue to operate in these
conditions.
In
some cases, overload and phase failure relays are used to protect three phase
motors from these ugly situations, by disconnecting the motor from the power
line but some components use in this techniques cannot perform fast switching.
Another
area where the detection and monitoring of three phase power lines are very necessary
is the utility power distribution transformers and poles. When there are
problems in street transformers or electric poles which lead to phase failure,
people usually accuse the power distribution company and start to change their loads
from one phase to another and at the same time overloading the
available phase.
ADACC Network based Three Phase Monitoring and Control device can effectively monitor the three phase line and notify the Utility Power Authority of phase imbalance or failure in
electric poles or transformers. The device can perform
the following:
1. It
assists the power distribution companies to maintain and deliver quality service
to their consumers.
2. If
implemented in machines, the system will turn off power to machine during the above mentioned power problems.
3. It will increase motor life.
4. It will help to reduce maintenance cost
of three phase motors and the risk of electric shock or fire due to the over stressed
motor winding.
5. It can be used for power line cable vandalism
detector system
This device can monitor the transformer temperature and oil level or other abnormal conditions.
